IP21s℃of protection Motor Z4-315-11-160kW-440V-IC06

1. Series and general design

This engine belongs to the seriesZ4independently excited DC motors, modelZ4-315-11. Rated power - 160 kW, rated voltage - 440 V, operating mode -S1 (constant), speed range - 600/1900 rpm. The motor is specifically designed for industrial DC variable drive systems and is suitable for a wide range of variable speed operating modes.

2. Cooling type IC06 (forced air cooling with independent channel)

The system is appliedIC06- forced cooling from an external independent fan. The cooling air is supplied by a separate fan; the engine itself does not have its own fan. Cooling performancedoes not depend on engine speed, so even at a low speed of 600 rpm, a stable flow of cooling air is ensured. This ensures stable winding and commutator temperatures, a key solution to preventing DC motor overheating at low speeds.

3. Protection℃IP21S

Degree of protectionIP21S:

Protection against solid objects with a diameter of more than 12 mm.

Protection against vertically falling drops of water (the letter "S" means that the test was carried out on a stationary device). This℃of protection is suitable forindoor, dry and dust-free industrial environments, providing a balance between effective ventilation and basic protection.

4. IM B3 installation design

Completed inhorizontal version with mounting feet (IM B3). Mounting dimensions fully comply with IEC standards, which ensures high versatility and alignment accuracy. Suitable for driving fans, pumps, rolling mills, machine spindles, winches and other equipment with horizontal installation.

5. Main electrical components

Armature winding: Designed for 440V nominal voltage, made of high-strength insulated wire with insulation class F. Capable of withstanding voltage fluctuations and switching loads during speed control.

Switching system: The Z4 series features high quality brushes and commutator for excellent commutation. Stable operation is guaranteed over a wide speed range (600-1900 rpm) with low spark generation, which reduces brush wear.

Stator excitation system: Independent excitation in which the field winding and armature winding are supplied from separate sources. Provides excellent speed control performance with smooth stepless control.

6. Mechanical structure and parameters

Engine weight -1900 kg. The high-strength cast iron body and durable covers provide high structural rigidity to withstand the shock loads of startup and speed control. Compact dimensions allow the engine to be installed in confined spaces at industrial facilities.

1.Wide range of smooth speed control, high performance at low speeds

Nominal speed range 600–1900 rpm. Paired with DC speed control system, realizes smooth stepless speed control. The motor maintains stable torque at low speeds without loss of power, ideal for rolling mills, winches, heavy machine tools and other equipment that require high torque at low speeds.

2.Forced air cooling IC06, stable temperature conditions at any speed

Cooling is carried out by a separate external fan, its efficiency does not depend on the engine speed. This eliminates the disadvantages of standard self-inflating engines: insufficient cooling at low speeds and increased aerodynamic losses at high speeds. The engine can operate continuously under full load even at 600 rpm, which significantly improves overall operational stability.

3.Good compatibility with 440 V DC networks

The rated voltage of 440 V fully meets the requirements of industrial DC power systems. Compared to low-voltage motors, this unit has lower operating current and minimal wiring losses, reducing cable costs and operating costs, ideal for high-power drive installations.

4.Protection class IP21S and continuous operation S1 for industrial use

The IP21S rating provides protection against large solid particles and vertical splashes of water in enclosed production areas, combining efficient ventilation and high reliability. Operating mode S1 allows round-the-clock continuous operation at increased loads.

5.Excellent connectivity and low maintenance costs

In the Z4 series, the design of the commutator and carbon brushes is optimized, a minimum level of sparking is achieved, the brushes wear evenly, which increases the intervals between scheduled maintenance. All consumable parts have standard sizes, are easily replaced and can significantly reduce repair and maintenance costs.

6.Robust design and high operational reliability

The engine weight of 1900 kg confirms the high rigidity of the structure, resistant to industrial vibrations and shock loads. The cast iron housing and high-strength bearings reduce noise and vibration during long-term operation, extending the overall life of all driven equipment.
